摘要：

目的 探讨放疗前肿瘤最大径、外周血中性粒细胞与淋巴细胞比值（NLR）对食管鳞状细胞癌患者放疗后发生食管瘘的预测价值。方法 选取2017年2月—2021年2月在中国科学院合肥肿瘤医院行放疗的食管鳞状细胞癌患者98例，根据随访过程中是否发生食管瘘将患者分为食管瘘组（13例）和无食管瘘组（85例）。计算放疗前预后营养指数（PNI）、NLR、全身炎症反应指数（SIRI）值。采用单因素和多因素logistic回归分析患者发生食管瘘的影响因素，采用受试者操作特征（ROC）曲线评估各项指标的预测价值。结果 食管瘘组与无食管瘘组患者年龄、吸烟史、糖尿病病史、性别、是否同步化疗、饮酒史差异均无统计学意义（均P>0.05），PNI（t=2.24，P=0.041）、NLR（t=3.75，P=0.001）、SIRI（t=2.68，P=0.015）差异均有统计学意义。单因素分析显示，肿瘤长度（OR=1.16，95%CI为1.01~1.35，P=0.043）、肿瘤最大径（OR=1.63，95%CI为1.11~2.39，P=0.012）、PNI（OR=0.83，95%CI为0.71~0.98，P=0.023）、NLR（OR=1.94，95%CI为1.20~3.12，P=0.007）、SIRI（OR=1.82，95%CI为1.03~3.24，P=0.041）均与食管瘘发生有关。多因素分析显示，肿瘤最大径（OR=2.17，95%CI为1.02~4.94，P=0.033）和NLR（OR=2.40，95%CI为1.89~6.59，P=0.018）均是影响食管鳞状细胞癌患者放疗后发生食管瘘的独立影响因素。ROC曲线分析显示，放疗前肿瘤最大径联合NLR预测食管鳞状细胞癌患者放疗后发生食管瘘的曲线下面积为0.83（95%CI为0.74~0.90），大于放疗前肿瘤最大径及NLR分别预测的0.71（95%CI为0.63~0.81，Z=1.80，P=0.039）、0.74（95%CI为0.67~0.85，Z=1.64，P=0.046）。结论 放疗前肿瘤最大径和NLR与食管鳞状细胞癌患者放疗后食管瘘的发生密切相关，有望作为预测食管鳞状细胞癌患者放疗后发生食管瘘的重要预测指标。

Abstract:

Objective To investigate the predictive value of maximum tumor diameter and the peripheral blood neutrophil to lymphocyte ratio （NLR） before radiotherapy for the occurrence of esophageal fistula after radiotherapy in patients with esophageal squamous cell carcinoma （ESCC）. Methods A total of 98 patients with ESCC who underwent radiotherapy in Hefei Cancer Hospital， Chinese Academy of Sciences from February 2017 to February 2021 were selected， and the patients were divided into esophageal fistula group （13 cases） and no esophageal fistula group （85 cases） according to whether esophageal fistula occurred during the follow-up process. The prognostic nutritional index （PNI）， NLR， and systemic inflammatory response index （SIRI） were calculated. Univariate and multivariate logistic regression were used to analyze the influencing factors of esophageal fistula， and the predictive value of each indicator was evaluated by using the receiver operator characteristic （ROC） curve. Results There were no statistically significant differences in age， smoking history， diabetes mellitus history， gender， concurrent chemotherapy and alcohol history between the esophageal fistula group and the no esophageal fistula group （all P>0.05）， while there were statistically significant differences in PNI （t=2.24， P=0.041）， NLR （t=3.75， P=0.001）， SIRI （t=2.68， P=0.015）. Univariate analysis showed that tumor length （OR=1.16， 95%CI： 1.01-1.35， P=0.043）， maximum tumor diameter （OR=1.63， 95%CI： 1.11-2.39， P=0.012）， PNI （OR=0.83， 95%CI： 0.71-0.98， P=0.023）， NLR （OR=1.94， 95%CI： 1.20-3.12， P=0.007） and SIRI （OR=1.82， 95%CI： 1.03-3.24， P=0.041） were related to esophageal fistula. Multivariate analysis showed that maximum tumor diameter （OR=2.17， 95%CI： 1.02-4.94， P=0.033） and NLR （OR=2.40， 95%CI： 1.89-6.59， P=0.018） were independent influencing factors for the development of esophageal fistula in patients with ESCC after radiotherapy. ROC curve analysis showed that the area under the curve of maximum tumor diameter before radiotherapy combined with NLR for predicting esophageal fistula in patients with esophageal squamous cell carcinoma after radiotherapy was 0.83 （95%CI： 0.74-0.90）， which was greater than that of maximum tumor diameter before radiotherapy （0.71， 95%CI： 0.63-0.81， Z=1.80， P=0.039） and NLR （0.74， 95%CI： 0.67-0.85， Z=1.64， P=0.046） alone. Conclusions The maximum tumor diameter before radiotherapy and NLR are closely related to the occurrence of esophageal fistula in ESCC after radiotherapy， and these factors are expected to serve as key predictors of the occurrence of esophageal fistula.
